What is it?
Facial fillers (aka dermal fillers, injectables) are injectable material used to restore facial volume which fall into two main groups: synthetic and natural. It can be made up of a variety of temporary, long- lasting, or more-permanent materials. Hyaluronic acid, a material typically used for temporary fillers, is a substance that is naturally present in the human body, and is either extracted or produced in the laboratory.
What does it do cosmetically?
Injected where there are wrinkles and lines, or sunken parts of the face, facial fillers immediately 'fill-in' the area and skin is plumped up to the point where the wrinkle, fold, or depression is gone. This cosmetic improvement can last anywhere between 3 months to 2 years (or even longer). This depends on the type of filler used, your skin texture, how you take care of your skin (e.g. sun exposure, smoking) and how your face continues to naturally age.
As a cosmetic/esthethic procedure, where are facial fillers applied?
Facial areas include the forehead, temples, superficial fine lines, nose (nasal bridge), brows, undereyes, cheeks, nasolabial fold, lips, smoker’s lines, pre-jowl sulcus, chin, Marionette (puppet) lines. Cosmetically, it is even applied to hands, feet, breasts and buttocks.
How long will it last?
Naturally-derived fillers consisting of hyaluronic acid have immediate results, however will typically last from just 3 to 18 months (and occasionally up to 2 years) because the filler eventually breaks down. Once the filler starts to dissipate, more filler injected is required to maintain results. Most people who get fillers will need at least one follow-up injection within a year.
Synthetic fillers last longer and are considered semi-permanent as they really don't dissipate. The wrinkles start to return only because of continual aging or sun damage.
What are the different types?
Temporary facial filler draw water which leads to tissue swelling and fullness. Popular brands (e.g. Juvederm, Restylane / Perlane, Teosyal) are bio-degradeable non-animal, lab-synthesized hyaluronic acid with little to no allergic reaction.
